THOMAS RODDIOK, OF STRANBAEB, SCOTLAND.

IMPROVEMENT IN OIL-CANS.

Specification forming part of Letters Patent No. 165,257, dated July 6, 1875 application filed April 24, 1875.

To all whom it may concern Be it known that I, THOMAS Ronmcrr, of Stranraer, Scotland, have invented certain new and useful Improvements in Oil-Cans; and

air-chamber above the oil-receptacle, from which airchamber a tube leads to very near the bottom of the oil-receptacle, in combination with an air-passage leading from the airehamber, through the neck of the can, to the outside of said neck, by which arrangement the oil in the can is allowed to flow out freely when the can is turned upside down or inclined, it being replaced by the air entering through the air-passage in the neck, conimunicating with the air-chamber above the oil-receptacle and the air-passage leading from the air-chamber to the lower part of the oilreceptacle. The air-passage leading from the outside of the neck to the air-chamber terminates on a collar or shoulder about halfway, more or less, of the depth of the air-chamber, so as to prevent the oil in the tube leading from the oil-receptacle to the air-chamber to run out through the air-passage in the neck when the oil-can is reversed. If any oil should enter the air-chamber when the can is turned upside down it will flow to the annular space around the top of the neck, and when the can is placed in its original position such oil will flow back again through the tube leading from the air-chamber to the oil-receptacle into the The neck is furnished with a deliverytube, as usual. The two air-passages above referred to are located directly opposite each other, so that a wire can be inserted through them in case they should get clogged up with dust, grit, or other impurities.

The accompanying drawing represents a central longitudinal section of my improved oil-can.

On the drawing, a represents the oil-receptacle, and b represents the air-chan1ber above it. 0 represents a wall or partition between them. 01 represents an air-tube leading from the chamber 11 to very near the bottom of the oil-receptacle a. 6 represents the neck of the can provided with an annular collar or proj'ection, f, as shown. The lower part of the neck 0 is soldered or otherwise united to the partition 0, through which a corresponding hole is made, so that the oil can flow out through the hollow neck e and its deliverytube 9 when the can is turned upside down or inclined. h represents the air-passage through the solid part of the neck 6, from the outside to the air-chamber b, which air-passage terminates at the collar f, for the purpose hereinabove set forth. The passage h is located opposite the tube 0?, so that both can be cleaned by passing a wire through them.

What I desire to claim, and secure by Letters Patent, is-

The combination and arrangement of the can a, annular disk 0, annular air-chamber b, neck e, withits collarf and air-tube h, located directly above the air-tube d leading from the chamber 1) to the oil-receptacle a, substantially as and for the purpose set forth.

In testimony thatl claim the foregoing as my own invention, I have affixed my signature in presence of two witnesses.
